Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PVC pipe weighing, in particular to automatic weighing and sorting equipment for PVC pipes. Background Art
[0002] PVC pipes are a common pipe fitting, widely used in daily life and industrial production. For example, dredging pipes and sewers, especially dredging pipes and sewers made of PVC materials, have gradually replaced metal pipes because of their light material, flame retardancy, good acid and alkali resistance, simple processing and durability. During the production process of PVC pipes, changes in equipment and processes will cause deviations in their dimensions. Once the dimensions deviate, the weight of each pipe will also change. If the pipe is too heavy, it means that the wall thickness exceeds the standard and wastes raw materials. On the other hand, the size may be too large, affecting the installation and use of the pipe. If the pipe is too light, it means that the wall thickness is too small, which poses a quality and safety hazard. On the other hand, the size may be too small, affecting the installation and use of the pipe. Therefore, it is necessary to weigh and classify the newly produced PVC pipes.
[0003] At present, when traditional PVC pipe weighing equipment weighs PVC pipes, the finished PVC pipes will automatically fall onto the weighing block. The long-term and large amount of PVC pipes will squeeze the weighing block, which will make the weighing block easily damaged, and cannot provide certain protection for the PVC pipes, and cannot classify and collect qualified or unqualified PVC pipes. Therefore, we propose an automatic weighing and sorting device for PVC pipes. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an automatic weighing and sorting device for PVC pipes. After the produced PVC pipes are transported between the first mounting plate and the second mounting plate, an external controller is used to control the operation of the first hydraulic cylinder, and the operation of the first hydraulic cylinder drives the second mounting plate to rotate downward. The first hydraulic cylinder translates under the limiting action of the limiting shaft and the first slider, and the first hydraulic cylinder also drives the L-shaped bracket to move downward. The downward movement of the L-shaped bracket drives the first rack to move downward, and the downward movement of the first rack drives the gear to rotate. The gear rotation drives the second bow frame to move upward, and the upward movement of the second bow frame drives the V-shaped bracket to move upward, so that the V-shaped bracket is used to receive the PVC pipe that slides off the second mounting plate, and then the piston rod of the first hydraulic cylinder moves upward to make the V-shaped bracket slowly move downward, and the PVC pipe is placed on the weighing block, so that not only can the weighing block be effectively prevented from being damaged when receiving the PVC pipe, but also can play a certain protective role on the PVC pipe during the automatic weighing process, and then the weighing block weighs the weight of the PVC pipe, and the classification component is used to classify and collect it, which can effectively solve the problems in the background technology.
